In the 48th minute of their 3-0 win over Honduras, the GoalControl system correctly ruled that France’s second goal should be awarded, despite it initially appearing that Honduran keeper Noel Valladares had prevented the ball from crossing the line after Karim Benzema's shot had hit the post.
Replays inside the stadium showed that Benzema's initial shot had not gone in before confirming that the ball had crossed the line after hitting Valladares' hand.
Deschamps believes there needs to be more clarity to avoid further confusion in the future.
"I think it is a good solution. We were just worried that on the screen they showed an image that didn't correspond to the goal,” he said.
"It was only after the goalkeeper pushes the ball into the goal it is a goal.
"The image shown must be the one that justifies the decision of the referee."
Prior to the game, France had won just one of their last nine games in the World Cup group stages – and Deschamps admits he is relieved to get off to a winning start.
"This is a very good start. We've had good times during our preparation, but this is the competition. Winning today is a very good start,” he told French television.
"We will enjoy this victory. A 3-0 win in the World Cup is never easy. We have been patient. We had our chance and hit the bar twice in the firstperiod.
"We did well. Congratulations to the players."
